[Bug 192653] Re: firefox 3 session restore and undo closed tab missing

[Pete Gillin]

In case anyone stumbles across this, as I just did, it seems to be a bug with FF3 and Tab Mix Plus which persists even if you uninstall the extension. I fixed it by:
(1) Uninstalling TMP,
(2) Closing firefox,
(3) Editing .mozilla/firefox/[profile-identifier]/prefs.js to delete all lines setting prefs for extensions.tabmix,
(4) Restarting firefox.
Why those prefs should continue having an affect after the extension is uninstalled, I don't know, but it seemed to work. Note that you must close FF before making the edit, or it will overwrite all your changes on close. (I can't see a way to remove entries entirely in about:config.)
